T all whom it may concern:

Be it known that 1, Former K. MILLARD, a citizen of the United States,and a resi- .dent'of -l?ittsburgh, in the county of Allegheny and Stateof Pennsylvania, have invented a ,new and Improved Puzzle, of which thefollowing is a description.

The general object of my invention is to provide a sectional puzzle madeup of a definite number of sections of given shapes, whereby the giventask of solving the puzzle may be varied within limits to add to theinterest of the puzzle. j

The nature of the invention will clearly appear from thespecificrdescription followmg. 7 I s 1 Reference is to be had to theaccompanying drawings forming apart of this specification, it beingunderstood that the draw: ings are merely illustrative of one example ofthe invention.

Figure 1 is a plan view of a sectional puzzle embodying elements formedin accordance with my invention and arranged to forma square;

Fig. 2 represents on a reduced scale another square formed by the sameelements differently arranged; v

Fig. 3 represents two figures formed from my improved sectionalelements, the two figures jointly employing all the elements of thepuzzle;

Fig. 4 is a plan view of another figure that may be formed from myimproved puzzle by employing all the elements thereof;

Fig. 5 represents in plan and side elevation one of the elements of myimproved puzzle.

In carrying out my invention I employ fifteen separate elements servinto jointly make up the sectional puzzle. fitIlOHS solutions of myimproved sectional puzzle are possible; the four solutions illustratedas examples will be particularly referred to in the following:

All the elements present a series of squares of equal size and adjacentsquares are distinguished from each other by suitable means. In theillustrated example I distinguish a square or squares of a given elementfrom the other square or squares of said element by a circle. Thearrangement i such that when the sections are properly assembled tojointly make up a figure rep-' resenting a given solution of the puzzle,squares of the respective elements will be disposed in the completefigure in amanner that those squares similarly distinguished willalternate. The squares in each element are defined by surface lines inconjunction with the defining edges of the element.

Patented June "2,1921.

The total of fifteen sections orfelem ents'i are employed to coniposethe puzzle and these are respectively designated in the assemblage ofFig. 1 by the numerals 11 to 25, inclusive. i l

Four L-shaped elements numbered 11, 12,

15 and 19 each presenting three squares are employed, some of saidelements presenting two squares similarly distinguished (by thecirclefor example) and a single square otherwise distinguished as byleaving the same plain, while in others of the said four L-shapedelements two squares remain plain and unmarked while the third isdistinguished by the particular means adopted, such as the circle. Theother elements of the puzzle are sisfollows: An L-shaped elementpresenting five squares, of which four are in line; one element, 22,presenting five squares of which four are disposed in the form of a Tandone at one end of the T- head and at the opposite side from that squareconstituting the shank of the T; one element, 20, presenting foursquares arranged in the form of a square, and a fifth square at one sideof one of the said four squares; two elements, 13 and 1 1, of T-shapepresenting four squares, that is, three in the head of the T, and onerepresenting the shank of the T; one element, 17, presenting six squaresof which four are in a row, .and two at the sides of the twointermediate squares in said row of four; one element, 24, presentingfour squares in a row and the fifth square at a side of one of thesquares and disposed next to an end square; three elements, 16, 21, and25, presenting four squares disposed in two overlapping rows of twosquares each; and finally, one element 23 presenting four squares in arow' and two squares at one side of said row,

said two squares beingspaced the distance i zle is afforded by Fig. 3,wherein two figures a e sh h on (at the left of Fi 3) made up of theelements 15, (or 11) '16, (or 21); 18; 19, (or 12); 22; and 25 (or 21);while the figure atthe right of Fig. 3 is similar to thatat the leftexcept that it has two additional, and longer rows of squares at thecenter, said figure at the right of Fig. 3 being made up ofthe elementsas follows: 11. (or 12; 13; 14; 17; 20; 21; 23 and 24.

In ig. at a further example is given of a figpre employing all theelements (1 to 25 V V Fig. 5 is yen to show one of the sectionalelements to wit; No. 25, which, as stated, 5

corresponds with 16 and 21 in shape.

I would state in conclusion that while the illustrated exampleconstitutes; a prac of equal size and defined jointly by surface. linesand the marginal edges of the respective elements, adjacent squaresbeing dietin guished, said elements presenting members puzzle comprisingfifteen ele-i and surface squares positioned to variously receivedifferent members and squares of others of said elements 1n a varlety oidistlnctlve assemblages, sald elements comprising thefollowing to wit;four Lsha-ped elements each presenting three squares; three elementseach presenting four squares disposed in two overlapping rows of twosquares each; two elements of T-shape presenting four squares; oneL-Shaped element presentmg five squares of which four are in line; oneelement presenting five squares of wh ch four are disposed as a T andone at one end of the T-head and at the opposite side from that squareconstituting the shank of the T; one element presenting four squaresarranged' as a square and a fifth squareat one side of one vof the, saidfour squares; one element presenting six squares of which four are in arow and two at one side of said row alongsidethe two intermediatesquares insaidrow; one element presenting four squares: in a row and afifth square at a side of one of the squares disr posed next to an endsquarein said row;

and one element presenting four squares in a row and two squares atoneside of the row said two squares being spaced the distance of onesquare and one of the two being adjacent to an end of said row.
